Newton's Second Law Experiment

This Java applet simulates an air track glider setup, as it is used for experiments on constant acceleration motion. A gravitational acceleration of 9.81 m/s2 was presupposed.

The mass of the wagon, the value of the hanging mass and the coefficient of friction (within certain limits) can be changed.

For one measurement you have to adjust the measuring distance (from the initial position to the light barrier LB, accuracy 5 mm) with pressed mouse button and to read the corresponding time (digital display, accuracy 1 ms). During the movement a red point in the t-s-diagram (time - displacement) indicates the present time and the covered distance. As soon as the measurement of time is finished, the pair of measured values will be marked on the diagram. After a mouse click on the "Record data" button the data will be registered on the list. A series of measurements with the same parameters cannot contain more than 10 measurements.
